摘要

选取催化重整18集总31反应集总动力学模型，以流程模拟软件HYSYS为工具，建立了催化重整机理模型。以最大化芳烃产率为优化目标，以4个反应器入口温度为决策变量，建立了过程优化模型。利用差分进化算法求解该优化问题，并利用可行性规则处理约束。仿真结果表明，芳烃产率有较大提高，证实了差分进化算法的有效性。

Abstract

A kinetics model involving 18 lumped components and 31 reactions was selected and a mechanism model was built based on HYSYS simulation software. To establish the process optimization model

the objective was to maximize the yield of aromatics and the decision variables were inlet temperatures of four reactors. The optimization problem was solved by differential evolution and the constraints were handled by feasibility-based rule. The simulation results demonstrated the increase of aromatics yield and confirmed the effectiveness of differential evolution.
